10 foot spikes of sand form in a 10 foot radius, suddenly rising from the area. Any creatures caught in it must make a Reflex save or take 1d6 points of piercing damage per technician level (maximum 10d6). These spikes may also come out horizontally, diagonally, or even down rather or as well as up at the technician's choosing and last 1 minute at which point they fall apart unless the technician reforms them with a Concentration check. The area becomes difficult terrain for all but the user and anyone moving through it takes 1d6 piercing damage from being scratched by the spikes.

By spending an additional 3 technique points and 1 cubic foot of attuned sand you may increase the radius of this ability by 5 feet. This may be done additional times.

By spending an additional 2 technique points you may extend the height of the spikes by 5 feet.
